 3. Chinese people are planting more trees now. Fill in the blanks according to the passage.
In 1620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn't want to copy the USA's example. We're planting more and more trees. We've built the "Great Green Wall" of trees across northern part of our country. The Great Green Wall is 4, 480 kilometers long, and between 560 and 1,460 kilometers wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More "Great Green Walls" are needed. Trees must be grown all over the world. The Great Green Walls will make the world better.
